Definitions
- the present invention relates to a fitting system for a vehicle seat, in particular for a motor vehicle seat, with the fitting system including a first fitting and a second fitting that are driven by a common drive shaft; each of the fittings having a first fitting part and a second fitting part that are connected to one another by a gear mechanism so that there can be a rolling movement of the second fitting part on the first fitting part, with an angle defined between the fitting parts and being changed by the rolling movement; and each of the fittings having a driver rotatably mounted in the first fitting part and driving an eccentric arranged so that rotation of the driver causes the rolling movement of the second fitting part on the first fitting part, when the driver is driven by the drive shaft.
- US 2005/0179297 A1 discloses a fitting system of the type described above, with two identical fittings, in which the driver necessary for the driving is of two-part design in the form of a driving bushing made of plastic and a driving ring made of metal.
- the driving bushing and driving ring are connected to each other in a rotationally fixed manner. For special cases, some features of the fitting system are unused and might be saved.
- a fitting system for a vehicle seat in particular for a motor vehicle seat, includes fittings, a drive shaft for driving both of the fittings, and a stopper.
- the fitting For each fitting, the fitting includes a first fitting part and a second fitting part that are connected to one another by a gear mechanism so that there can be a rolling movement of the second fitting part on the first fitting part, an angle is defined between the first fitting part and the second fitting part, the angle is changed by the rolling movement, and the fitting further includes a driver and an eccentric, wherein the driver is rotatably mounted in the first fitting part for driving the eccentric, and the eccentric is arranged so that rotation of the driver causes the rolling movement of the second fitting part on the first fitting part when the driver is driven.
- the drive shaft is more specifically for simultaneously driving both the driver of a first of the fittings and the driver of a second of the fittings.
- the stopper is mounted on the first fitting for limiting at least the angle defined between the first fitting part of the first fitting and the second fitting part of the first fitting.
- the driver of the first fitting is made of a material with a high mechanical strength and the driver of the second fitting is made of a material with a lower mechanical strength.
- the driver of the first fitting is made of a material with a high mechanical strength, e.g. metal, and the driver of the second fitting without a stopper can be made of a cheaper material with a lower mechanical strength, e.g. plastic, thereby reducing the production costs for the fitting system.
- using the second fitting has the advantage that in case of an impact load (e.g. crash), the load from the backrest does not easily pass the second fitting but is received by the gear mechanism between the two fitting parts.
- the load path is the same for both fittings. The load is carried between the two fitting parts and wedge segments without passing the drivers.
- the motor can be advantageously mounted closer to the first fitting with the stopper than to the second fitting without a stopper or mounted on the side of the first fitting faced away from the second fitting. This has the advantage that the first fitting with its driver and its stopper absorbs the motor stall force. It also minimizes the torsion of the drive shaft, so both fittings are stopped simultaneously.
- the fitting system according to the invention is preferably designed for a motor drive, but it may also be driven manually.
- the invention can also be used in other gear-type fittings which are driven by motor or manually, irrespective of whether an eccentric made from wedges or a substantially rigid eccentric is provided.
- FIG. 1 shows a sectional view of the fitting system with a first fitting on the right side and a second fitting on the left side,
- FIG. 2 shows an exploded illustration of the first fitting
- FIG. 3 shows a partially sectional view of the first fitting in the direction of the arrow III in FIG. 1 ,
- FIG. 4 shows a schematic illustration of a vehicle seat having a fitting system according to the invention
- FIG. 5 shows a perspective view of the first fitting when the stopper is mounted
- FIG. 6 shows a view of the driver of the first fitting in the direction of the arrow VI in FIG. 7 ,
- FIG. 7 shows an axial section through the driver of the first fitting along the line VII-VII in FIG. 6 .

- FIG. 11 shows a view of the driver of the second fitting in the direction of the arrow XI in FIG. 12 .
- FIG. 12 shows axial section through the driver of the first fitting along the line XII-XII in FIG. 11 .
- a vehicle seat 1 for a motor vehicle has a seat part 3 and a backrest 4 that can be adjusted in its inclination relative to the seat part 3 by an electric motor 5 .
- the motor 5 (which is schematically illustrated in FIG. 1 ) is fitted on the structure of the backrest 4 and functions as a drive for the inclination adjustment.
- the electric motor 5 rotates a drive shaft 7 which is arranged horizontally in the transition region between the seat part 3 and backrest 4 .
- the electric motor 5 is arranged on one side of the vehicle seat 1 , called the driving side.
- the opposite side of the vehicle seat 1 is called the driven side.
- the drive shaft 7 engages (in a way which is described below) in a rotationally fixed manner in a fitting, i.e. on the driving side, the drive shaft 7 engages a first fitting 10 a (recliner), and on the driven side, the drive shaft 7 engages a second fitting 10 b (recliner).
- the drive shaft 7 defines the cylindrical coordinates used below.
- Each of the two fittings 10 a , 10 b is designed as a geared fitting, in which a first fitting part 11 and a second fitting part 12 are connected to each other for adjustment and fixing purposes via a gear mechanism.
- the two fitting parts 11 and 12 have an essentially flat shape and consist of steel.
- the first fitting part 11 is connected fixedly to the structure bearing the driving electric motor 5 (in the present case the structure of the backrest 4 ), for which reason, in the exemplary embodiment, the first component 11 is fixed on the backrest and is therefore illustrated at the top in the drawings.
- the second fitting part 12 is fixed on the seat part and is illustrated at the bottom in the drawings. In the case of a different arrangement of the electric motor 5 and with manually driven fittings, the positions of the fitting parts 11 and 12 can be interchanged.
- a gearwheel 16 having external teeth is embossed on the second fitting part 12
- a gearing 17 having internal teeth is embossed on the first fitting part 11 , with the gearwheel and gearing intermeshing.
- the diameter of the outside circle of the external teeth of the gearwheel 16 is smaller by at least one tooth height than the diameter of the root circle of the internal teeth of the gearing 17 .
- the corresponding difference between the number of teeth of the gearwheel 16 and gearing 17 enables the gearing 17 to roll on the gearwheel 16 .
- the first fitting part 11 has, concentrically with the internal teeth of the gearing 17 , an integrally formed collar 19 on the side facing the gearwheel 16 .
- the first fitting 10 a comprises a driver 21 a
- the second fitting comprises a driver 21 b .
- Each driver 21 a , 21 b is rotatably mounted in the collar 19 of the corresponding fitting 10 a or 10 b by means of a hub 22 .
- the hub is provided in the center with a hole 23 .
- the profile of the hole 23 is matched with the profile of the drive shaft 7 , namely the external splines of the drive shaft 7 .
- the driver 21 a of the first fitting 10 a is made of a material with a high mechanical strength, e.g. metal, more specifically by metal injection molding (MIM) process carried out with steel, zinc, or aluminum powder and that includes a sintering step after the molding step.
- the driver 21 a can also be made of a fiber-glass reinforced plastic with more than 50% fibers.
- the driver 21 a is provided with an integrally formed covering disk 25 a that has a diameter that is larger than the diameter of the hub 22 .
- the driver 21 b of the second fitting 10 b is made of a material with a lower mechanical strength, e.g. plastic (e.g., polymeric material), more specifically by injection molding the plastic.
- the driver 21 b can also be made of a fiber-glass reinforced plastic or zinc injection molding.
- the driver 21 b is provided with an integrally formed covering disk 25 b that has a diameter that is larger than the diameter of the hub 22 .
- the diameter of the covering disk 25 b is larger than the diameter of the covering disk 25 a.
- Each fitting 10 a , 10 b is provided with two wedge segments 27 .
- the wedge segments 27 are supported, by way of their curved inner surfaces, on the collar 19 , with the wedge segments 27 supporting, by way of their curved outer surfaces, a sliding bearing bushing 28 .

- the annular spring 36 pushes the wedge segments 27 apart in the circumferential direction.
- the spring 36 is kept in its position relative to the wedge segments 27 by a spring fixing washer 37 .
- Each driver 21 a , 21 b is secured axially on the outside of the respective first fitting part 11 by way of a clipped-on snap ring 43 .
- a sealing ring 44 a , 44 b is provided on the outside of the respective second fitting part 12 , between the embossing for the gearwheel 16 and the corresponding covering disk 25 a , 25 b of the driver 21 a , 21 b .
- the sealing rings 44 a , 44 b seal between the second fitting part 12 and the corresponding covering disk 25 a , 25 b .
- the inner diameter of the sealing rings 44 a , 44 b are adapted to the diameter of the corresponding covering disk 25 a , 25 b .
- brackets 45 are respectively welded onto each of the two fitting parts 11 and 12 .
- bracket 45 it is welded to one of the two fitting parts 11 and 12 , and it engages over the other of the two fitting parts 11 and 12 without obstructing the adjusting movement.
- FIG. 1 only one of the brackets 45 is illustrated in FIG. 1 .
- the wedge segments 27 define an eccentric that presses the gearwheel 16 in the direction of the eccentricity into the gearing 17 at an engagement point.
- a torque is initially transmitted to the driver 21 a , 21 b and then to the thus defined eccentric which slides along the sliding bearing bushing 28 displacing the direction of the eccentricity and therefore displacing the engagement point of the gearwheel 16 in the gearing 17 , which provides a tumbling rolling movement.
- the first fitting 10 a is provided with a stopper 51 arranged on the surface of the first fitting part 11 facing away from the second fitting part 12 .
- the stopper 51 comprises a stopper body 53 having shape more or less like (e.g., substantially like) a half ring. Teeth projecting radially to the inside come into engagement with the backside of the gearing 17 , thus prepositioning the stopper 51 on the first fitting part 11 during assembling.
- the stopper 51 and the first fitting part 11 are welded together at the locations of these two toothed engagements and at the upper edge of the stopper 51 .
- a stopper bolt 55 is mounted to the stopper body 53 , and the stopper bolt 55 is axially projecting away from the first fitting part 11 .
- the passenger can use the vehicle seat 1 within a certain range of so called use positions of the backrest 4 corresponding to different inclinations of the backrest 4 .
- the electric motor 5 drives the fittings 10 a , 10 b to change the angle between the fitting parts 11 and 12 and thus to adjust the inclination the backrest 4 , i.e. to change the use position of the backrest 4 .
- the stopper 51 comes into contact with a counter stopper at the seat part 3 . More specifically, the stopper 51 comes into contact with the lower bracket 45 (e.g., counter stopper) attached to the second fitting part 12 .
- the electric motor 5 stops.
- the stopper 51 limits the angle between the fitting parts 11 and 12 .
- the corresponding driver 21 a receives a larger load than the driver 21 b of the second fitting 10 b without stopper 51 .
- the driver 21 a of the first fitting 10 a is made of strong metal
- the driver 21 b of the second fitting 10 b is made of cheaper plastic.
